GURPS: Spaceship Control Room Question

[Ulzgoroth]

My own hack for extended bridge space is to use passenger seating and charge an extra 50k per seat converted to a control station. That way you're not re-buying any unwanted features.

I'd only pay full price for an extra control room if it was supposed to be a fully independent auxiliary control, like the secondary bridge on Honorverse warships. Even then it may be a bit much considering that supposedly includes a lightweight sensor array and attitude thruster system.
